Who is the author of the novel that features a shipwrecked man living on an island for over 20 years?

The author of the novel featuring a shipwrecked man living on an island for over 20 years is Daniel Defoe. This narrative is famously represented in his novel "Robinson Crusoe," which delves into the themes of survival, self-sufficiency, and human resilience in the face of isolation.

Defoe's storytelling explores the protagonist's struggle for survival and personal growth during his time alone on the deserted island, providing insights into human nature and the instinct to adapt. The character's ingenuity and determination in transforming his environment reflect the broader themes of adventure and enlightenment during the time of Defoe's writing.

Other authors listed, such as Charles Dickens, Miguel de Cervantes, and Fyodor Dostoyevsky, are known for their distinct contributions to literature, but their works do not center around the premise of a man shipwrecked and living in isolation in the way that Defoe's "Robinson Crusoe" does.
